Evolution of micropyles in dragonfly eggs (Anisoptera)
Odonatologica , Volume 19 - Issue 3 p. 235- 241
In a series of Anisoptera eggs examined, the number of micropyles per egg generally decreased from 14 in Petaluridae to 2 in Libellulidae, and a tendency to concentrate micropyles at the tip of a micropylar stalk was noted. Both of these features may allow more efficient and rapid fertilization of eggs as they are laid.
